When looking around, a majority of people have black or brown hair. Then there are people with blonde hair, and finally the color you see the least, are those with red hair. What if you could have the chance to tell if your future child would have red hair, would you?
BritainsDNA, is a British company that can test your genes and in fact tell you if your child will inherit the red hair color gene. Both parents would have their tested to look for the gene MC1R, that causes people to have red hair. This is done by a saliva test in order to find out if one or both of the parents are carriers of any variation of the MC1R gene. From simple genetics, since they are testing if the parents are carriers, the MC1R gene from both parents would need to be passed down to the child, as it is a recessive gene. But even so, this does not mean that the child would automatically have red hair. This would just mean that there is a 1 in 4 chance of having red hair.
The population of people with red hair is just over 0.5 percent, worldwide. This means that people with red hair are very rare, about 1 in 200 people rare. In other words, that is approximately 40 million people in the world! If you have a red headed friend, you might want to tell them how special they are! And if you don not, would you be interested if you have the possibility of having a red haired child?
